Pixel dating

You know what I would like to be able to do: pixel dating! No, I’m not referring to two pixels having fun at the singles club; I’m talking about being able to determine the date a pixel in a digital image was last edited.  Imagine if every single pixel in a digital picture had an inherent temporal signature. A signature that would indicate the last time that specific pixel had been altered. Newer pixels from the original image would glaringly pop-up, revealing their real age, against the backdrop of the sagging and desperate "older" pixels.

It's a bit like the radiocarbon dating archaeologists use to determine the age of artefacts, only for geeks.  Elle, I would have so much fun exposing the cosmopolitan extent of the "face-lifting" done on some photos.  People would pay me copious amounts of money to expose "rejuvenated" pixels. I would live in a large penthouse like a playboy for the rest of my life.

To what end, you might ask, do I wish to possess this pixel dating skill?  I'll tell you: isn't it time we got real.  Are we that artificial and shallow that we cannot even enjoy the true reflection a photograph provides?  If I was a photographer for a fashion or glamour magazine, I would be seriously concerned if someone "washed" all the imperfections from my art.  Not to mention what the model in the photograph must feel like.

Note:  Pixels are those tiny little squares that make up a digital image.  That’s the simple explanation, for a more technical explanation Google it!

I personally believe the idea is not that far fetched. The netto impact does not have to be 7 bits per pixel. As the author rightfully stated using a signature based history of the original footprint of the image one should be able to track the changes (bit level technology enhanced).

Just add a crc/checksum to the end of the image data and encrypt the crc with a key only known to the photographer. If the data/pixels change the crc will not verify
